Costco adds new warehouse as shares near 50-day average

Costco is pushing ahead with its warehouse expansion, adding a new store after opening in Albany and lining up another opening in August as the retailer keeps leaning on steady traffic and new square footage to support sales growth.
The openings matter because Costco has been using new warehouses to offset pressure from mature markets, where cannibalization can dilute gains at existing stores. In its latest quarterly filing, the company said comparable sales were helped by new warehouse openings, and that square footage growth remains a key driver of the business.
For investors, the expansion underscores Costco’s playbook of trading near-term capital outlays for longer-term membership revenue and volume growth. The stock has been volatile over the past several months, but the latest price at $947.82 sits just above its 50-day moving average of $950.28 and near its 200-day moving average of $955.26, suggesting the shares are consolidating after a sharp run earlier in the year.
The broader backdrop is still supportive for discretionary and bulk-retail spending. Adalytica’s consumer spending sentiment is at 100, or “Extreme Greed,” while the S&P 500 trade signal also sits in “Extreme Greed,” pointing to a risk-on tone that can help premium retailers with strong value propositions.
Costco’s latest opening comes as Walmart’s earnings sentiment has slipped into “Fear,” highlighting how the club model can continue to differentiate itself from broader retail peers even as competition for price-conscious shoppers intensifies. Costco remains focused on opening new clubs, growing membership and driving traffic, rather than relying on aggressive promotions.
The next catalysts are execution at the new locations, monthly sales updates and any further guidance on warehouse openings, which will show whether the company can keep converting expansion into higher revenue without eroding returns at existing stores.
